 Haploj)hragmium glomeratum, Eobertson, 1880, Proc. Nat. Hist. Soc. 



Glasgow, vol. V. p. 12. 

 This is probably not an uncommon form on muddy bottoms, but may 

 be easily overlooked by reason of its minute size and inconspicuous 

 characters. As a British species it was first noticed by Mr. Eobertson in 

 Portree Bay, Skye ; subsequently by Mr. Wright in Killybegs Harbour, 

 Donegal ; and by Messrs. Balkwill and Wright at several points in the 

 Irish Sea.

I am not prepared to say what is the precise position and relationship 



of this organism ; but I beheve Mr. Siddall's specimens to belong to the 



species described many years ago by Mr. Carter under the name 



Squamulina varians, and treated by him as a near ally of Ealiphysema
